EV-.APORATIVE COLER.

To all whom it may concern: i I

Be it known that I, LAURA IDA OOLLETT, e citizen of the United States, residing at. W'alker, `in the county of `Vernon and State of Missouri, have invented certain new and useful lnun'm-*ements in Evaporativ'e Coolers, .of which the following is a specificetion, reference being had to the accompany- ,ing drawings.

rlhis invei'ition is an. improved milk cooler ofthe writer evaporation cnpillry feed type,` for utilizing the evaporation of water re.- sulting from the melting of ice in an ice hex, for keepii'lg milk or other articles or substances cool, the object of the invention being to provide an improved device of this character which is strong and durable, may be readily kept clean, and muy be readily i taken 'apart for the purposes of repair, und renewal or othcrreesons, the invention consisting in the construction, combination and arrangement. of devices hereinafter described :1nd cluii'ned.

In the accompanying drawings-Figure 1 is a perspective View of e n'lilk cooler constructed in accordance with my invention,

the curtain on the frontA side thereof being shown partly removed. Fig. 2 is is a vertical.. longitudinal sectional view of the saine. Fig. 3 is a det-ail perspective View showing one corner ot the upper tray, Fig. 4 is e, similar view showing a portion of one of the legs of the traine, and Fig. 5 is a vertical transverse sectional view of the upper portion of the inilk cooler.v Fig. 6 is e detail sectional view on'the plane indicated hy the line G--G of Fig. 2. Fig. 7 is e similar View on the plane indicated by the line b-b of Fig. Q.

The lower troy' l which ornis the 'base of my improved milk cooler is provided vat its corners with supporting feet 2, and is here shzwn es provided withs-hgmdles 4.3 at its en s.

The upper tray 4 is supported on the upper ends 'of inclined, upwardly converging legs 5. each of which is made of sheet meto and. is substantially L-sheped in cross sec tion. Each leg is provided on its inner side nt suitable distances apart with supporting lbrackets 6 which are also made ofsheet metal, preferably copper or gelvenizediron, und nrc provided on their upper sides with studs 7,. lt will he understood that these brackets serre to' strengthen the construction Specification of Letters Patent.

are disposed in the 'corners of the lower troy` 1. vThe upper troy 4 bears on the upper Iatented Apr.' 4, 1911.

ends of the said legs and is provided on its under side etits corn-ers with outer and inner posts 8,-9 which are L-shaped cross sectionally-and appropriately spaced apart so es to receive the upper en s oi the legs between thern, and to bear re ectively on the outer and. inner sides ofv the eg's. Hence the lower tray 1 the upper troy 4 and the legs 5., Y. In connection Y with this'frame, I employ a number of sup- Vform a. supporting freine.

poi-ting shelves 10 which are here shown -as made of corrugated sheet metal. They may be ma de of any suitable material, galvanized iron being well adapte-d for this' purpose.

These shelves 10 vary in size, and are sup-' ported by disposing their corners on the brackets 6 within the angles 'of the legs 5,

the said shelves being provided near their corners with openings for the reception of the studs 7 so that the shelves serve to secure the legs in position, and are at the same time enabled to be readily removed when this is desired.

The. upper tray 4 supports-a suitable vessel which is'hcre shown as an ice 00X or ice chest 1l, provided with `a-hing'ed lid 12, .a chain 13 to support the lid, in o ed posltion, and staples 14 on the lid an front side of the chest in connection with which o suitable lock maybe employed ii desired to lock the lid' in closed position. The ice chest is formed with outer und inner wlls and suitidole nonvcondu'cting material packed botween them. At oneend 'of the chest is e fencct 15 which permits the discharge of water from the chest resulting from .the

melting of ice therein.. The ice chest is here shown as provided with a'. sheetinetnl fnlsebottom llto support vthe ice and with downturnedsnpporting end `flanges 17, and

`a medially disposed supporting wall '1 8'.

Openings-19 are indicated in theialse bottom for` the' passa-ge orwater therefrom end for the insertion otthefingers there-. lthrough vto facilitate the retrieval of theaielse' also bottom, when this is desired. i

.Curtains 20 Whch cover 'the freine and' bear on the-outer'sidesof thele'gs 5. heve their upper-ends doubled over the Wells ogt-he upper tray 4 suitable' means such yfor instance es 'ev the, clilrtain's .end hooksvQL on 'the inne of thehwallsof thefsgiidqtrayaisnt the Cnrta @s 11d d es in idee and attached thereto @I ly l' 4xi' the two back :1Q an -the ice chest, the latter ',water. Any' suitable vessel or means may be into the tray and become saturated with the Water ltherein. The curtains are fastened at the two front corners of the frame by means of 4suitable clasps and are sewed together at corners of the frame. They may be attached, however, to the frame by any suitable means, or in any suitable manner and I do not 'desire to limit myself in this particular. The front cutaln comprises upper section 22, and a lower section 23. The uppersection, the lower portion of `which overhangs the upper portion of the .,lo'wer section, is provided at its lower edge 4with a ring' or other suitable attaching dc- 'vic'e 2, which 'W en" the upper section of the front curtain is raised. may be engaged "ivith a knob 25 on the'flifl 'of the ice chest so asto support'-the said upper section in uraised position.

The lower section may.. he ''lQWere-d. from its upper side, and bv thus milking the. front curtain in sections. an)7 one' of the compartments 'formed in the supi 'portinor frame between the shelves l0 may reached Without the necessitv of uncover'ine: allof the said-compartments. and admittinewarm air thereto.

In 'the operation ot' mr invention. the millar for" other articles to' heilt/mt cool. is olaeel on thevarious shelves andthe. curtains are closed. The ice 1n melting in the ice chest causes the unpertrav 4 to become tilled with water'the tl'ow jot which into the trav 4 is' and' keeps the curcontrolled bythe faucet 15 causes an evaporatainssa-tiia ted, and hence `tion lwhich is 'utilized for 0rother 'articlescool If no ice is used in may 'be supplied with employed "in lieu'of the ice chest for proy l viding 'thelvupper overflow traywith Water. `'Such Water as doesnot evaporate during its keeping the milk passage down through the curtainsflows into the receiving;r or bottom tray l, ancLmay be removed therefrom from time to time.

While I have shown herein the preferred embodiment of my invention, I `would have it understood that modifications may be made within the scope of the appended claims.
